Capt. John Braddock worked in the racket squad of a large metropolitan police department. He did not deal with crimes of violence but instead sought to protect the public from the various confidence rackets that were a more direct threat to them than outright robbery. The series was based on actual case records from police departments around the country and described in detail the means by which shady characters fleeced unsuspecting people of their money. Reed Hadley, in addition to his role as star, provided the narration for each episode. Hadley had previously been seen in a syndicated version of Racket Squad that was produced in 1950, a year before CBS decided to give the series network exposure.
